will the one wire alt. do ok in my 1950 f3 with flat head v8, thanks in advance

 

yes, the one wire is the way to go.

 

How does one go about converting an original 3-wire generator to a single wire alternator? I've been contemplating the switch, and my impatience and lack of spending cash wants me to go with the 6 volt.

 

There are a few places that sell 6v/pos. ground alternators. Since they use a custom internal regulator, this is something you have to buy ready-to-go. 1-wire or 3-wire, whatever they sell is what you get. No big deal either way, they are a huge improvement over a generator IMO.

There are some issues getting one that lines up with the truck WPs. See here for instance:

i had that trouble when i put one on the 239 flat head. i just cut the mounting ear on the long part of the alt. just enough to line up with the pully. it line up perfect and had no trouble.
